The laser cutting die includes a die placed on the periphery and a cutting die installed inside the die. Figure 1 As shown, the cutting die includes a cutting die pad and a cutting die core plate 1 installed on the cutting die pad. Since the cutting die core plate 1 is composed of a cylindrical tool 2, during the stamping process, after the upper die in the mold is stamped, the waste material remaining on the surface of the upper die is discharged from the front of the cutting die core plate 1, which can easily cause the remaining waste material to scratch and damage the surface of the workpiece being processed, thereby reducing the accuracy of the workpiece being processed. In addition, since the tool inside the cutting die core plate 1 is circular, it is easy for the installed tool to tilt during installation.
